The paper explains the conceptual framework of so called costs, effects and resources map that is intended to support performance analyses of the production value stream. Its purpose is to enhance manufacturing decision taking processes by providing relevant information related to production flows. The tool consists of five modules: production system model (value stream map), cost module, financial statement and inventory valuation module, resources analyses module, and operational metrics module. The tool has been equipped with appropriate metrics that enable analyses of production system dynamics. In the last section of the paper example application of the tool in the production environment has been explained.
